Venus was made of lava and was not ‘Earth-like’ after all, stunning study says



Final month, new hope arrived within the type of a research that Venus could have been liveable and was dwelling to “liquid water” for two to three billion years.

Now, that hope has seemingly been dashed, with the water changed by lava, in line with a brand new research.

The brand new analysis, revealed within the Journal of Geophysical Analysis: Planets, means that the second planet within the photo voltaic system was crammed with lava. This comes after they re-examined Venus’ Ovda Regio highlands plateau, which they consider was made up of basaltic lava.

“We all know so little about Venus’ floor,” mentioned the research’s co-author, Allan Treiman, in a press release. “If the Ovda Regio highlands are manufactured from basaltic rock as is most of Venus, they had been probably squeezed as much as their present heights by inside forces, presumably like mountains which outcome from plate tectonics on Earth.”

The staff discovered that the movement seen within the Ovda Regio highlands plateau was “not granitic as was anticipated from its location,” heightening the probabilities it was made up of basalt rock.

“The excessive‐altitude area of Ovda Fluctus is steady with the decrease‐elevation parts: the change in radar properties doesn’t symbolize completely different flows,” the research’s summary states. “Outlines of Ovda Fluctus movement lobes have fractal dimensions per basaltic pahoehoe lavas. The margin of Ovda Fluctus is at considerably increased elevation than its middle, a attribute seen in basalt flows on Earth, however not on extra silica‐wealthy flows.”

Skipping to the current day, Venus, which has been known as “Earth’s evil twin,” has a particularly harsh local weather, with a  floor temperature of 864 levels Fahrenheit.

The brand new research from Treiman and the opposite researchers follows one which was offered on the European Planetary Science Congress final month. This research indicated Venus could have had “liquid water” for two to three billion years till a “dramatic transformation” began occurring greater than 700 million years in the past that utterly reshaped the planet and resurfaced roughly 80 % of it.

The dramatic transformation led to a mass explosion of carbon dioxide on the planet between 700 million and 750 million years in the past, an occasion researchers say could also be linked to the volcanic exercise on the planet.
